Well, I've read a few case painting guides, however most of them achieve the high glossy look... which is not what I want. I just purchased a Coolermaster Stacker stc-101 from a friend of mine for 40 bucks... and this is going to be the first case that I have ever bought myself. However I do not like the colour silver... it doesn't feel... right...

The outer shell of the case is aluminum with a brushed finish. I want to keep the brushed look, but I don't want the silver look. Do you guys have any idea how to get by this? I think adding primer would fill in these gaps... which isn't what I want, however I've heard that the paint doesn't stick well onto metal because of how paint dries up, thus we add primer...

I want this to be a DIY project.

What do you guys think? Could I just paint it black and see what happens?

you can't paint and have a brush effect , you have to clean, electrolyze, stain it and after boil the parts to seal the pores. you may have an other solution ; I will test it tomorrow on the left over of the hole I do today in a similar case.

You would need to use oven cleaner then anodize it. A. Spraypaint (or any other paint) will fill the cracks and B. Once coated (sealed, w/e) its basically a smooth finish anyways. No matter how fine the paint, with that protective layer on it will never, ever work (and it won't work without it anyways).
